Description

The present invention relates to a connecting structure of a long material that connects two long materials.

Conventionally, as a connecting structure of a long member for connecting two long members, for example, a first plate arranged so as to straddle the outside of two beam members connected in the longitudinal direction and two pieces. It has a second plate that is arranged to face the first plate with the beam member in between, and two beam members by tightening nuts to the first plate, the second plate, and the bolt that penetrates the beam member. A joint structure of beam members connecting the above is known (see, for example, Patent Document 1). Since a large load acts on the beam, a large number of bolts are used when connecting with bolts and nuts via a member straddling the two beam members.

Japanese Unexamined Patent Publication No. 4-166527

When a large number of bolts are used as in the joint structure of the beam members, each bolt is inserted into the first plate, the second plate, and a plurality of members such as the beam member. It is difficult to insert a bolt in a state in which a large number of holes for inserting a bolt, which are provided for each, all overlap. For this reason, for example, bolts must be inserted through holes provided at distant positions, and bolts must be inserted and tightened while considering the tightening order of each bolt. Further, when a bolt in a certain hole cannot be inserted into another hole by tightening the bolt, the bolt that has already been tightened must be loosened and re-tightened, which causes a problem that the work is complicated.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a connecting structure of long members capable of easily connecting two long members.

In order to achieve such an object, the connecting structure of the long material of the present invention has two long materials and a long material connecting material hung over the two long materials, and each of them has a connecting structure. The long material has a reference hole on the long material side as a reference and a plurality of insertion holes arranged based on the reference hole on the long material side and through which bolts are inserted, and the long material connecting material. Has two reference holes on the connecting material side as a reference and a plurality of screwing holes arranged based on the reference holes on the connecting material side and into which the bolts are screwed. It is a connecting structure of a long material, characterized in that the positions of the holes and the positions of the reference holes on the long material side of each of the long materials are connected in a state of being coincident with each other.
Other features of the present invention will be clarified by the description in the present specification and the accompanying drawings.

Next, a method of connecting the two beam members 30 will be described.
As shown in FIG. 10, when connecting the two beam members 30, first, the lower surface portion 30f of the two beam members 30 and the lower outer surface portion 31b side of the beam connecting member 31 are arranged so as to face upward. (Beam member arrangement step S1). Next, the beam connecting member 31 is inserted into the hollow portion 30b of one of the beams 3, and the tapered portion 9b of the pin 9 is inserted into the beam side reference hole 30j and the connecting member side reference hole 31c. Next, the opposite side of the beam connecting member 31 is inserted into the other beam 3, and the tapered portion 9b of the pin 9 is inserted into the beam side reference hole 30j and the connecting member side reference hole 31c on the other beam side.

Next, the pin 9 through which the tapered portion 9b is inserted is driven by a hammer or the like to fit the cylindrical portion 9a of the pin 9 into the beam side reference hole 30j and the connecting member side reference hole 31c (pin fitting step S2). At this time, the edges 30a of the two beams 3 are abutted against each other and are in contact with each other, and the beam insertion holes 30k and the screw holes 31d are substantially centered and overlapped. Therefore, the columnar portion 9a of the pin 9 is formed to be longer than the total thickness of the wall thickness of the lower surface portion 30f of the beam member 30 and the wall thickness of the beam connecting member 31.

Next, the bolts 7 are inserted into the four beam insertion holes 30k located next to the fitted pins 9 and screwed into the screw holes 31d, respectively. In this state, the two beam members 30 and the beam connecting member 31 are joined on the lower surface portion 30f side of the beam member 30.

Next, the lower connecting member 32 is placed on the lower surface portion 30f of the two beam members 30 so that the contact plate portion 32a of the lower connecting member 32 straddles and contacts the lower surface portion 30f of the two beam members 30. Place in. At this time, the lower connecting member 32 is arranged so that the reinforcing material insertion holes 32c provided in the lower connecting member 32, the beam insertion holes 30k through which the bolts 7 are not inserted, and the screwing holes 31d overlap each other. .. Next, the bolts 7 inserted through the overlapping reinforcing material insertion holes 32c and the beam insertion holes 30k are screwed into the screw holes 31d (lower joining step S3). In this state, the two beam members 30, the beam connecting member 31, and the lower connecting member 32 are integrated.

Next, a drill is sequentially applied to each position indicating hole 32d provided in the lower connecting member 32, and the contact plate portion 32a of the lower connecting member 32, the lower surface portion 30f of the beam member 30, and the beam connecting member 31 are formed. A pilot hole for the drill screw 8 is formed so as to penetrate the lower outer surface portion 31b and have a diameter slightly larger than that of the position indicating hole 32d. Next, the drill screw 8 is screwed into each prepared hole formed. In this state, the lower surface portion 30f of each aluminum beam member 30 is sandwiched between the lower outer surface portion 31b of the beam connecting member 31 made of aluminum-zinc alloy plated steel plate and the abutting plate portion 32a of the lower connecting member 32. In this state, the state becomes closer (drill screw screwing step S4). Here, the lower outer surface portion 31b of the beam connecting member 31 and the abutting plate portion 32a of the lower connecting member 32 correspond to two connecting plate portions that sandwich the plate-shaped portion from both sides. Further, the pin 9 may be removed after the drill screw 8 is screwed.

Next, the two integrated beam members 30, the beam connecting member 31, and the lower connecting member 32 are arranged so that the upper surface portion 30i side of the beam member 30 faces upward.
Next, the beam decorative material 34 is placed on each of the two beam members 30, and the decorative material insertion hole 34a provided in the beam decorative material 34 and the beam insertion provided in the upper surface portion 30i of the beam member 30 are provided. The bolts 7 inserted through the holes 30k are screwed into the screw holes 31d (upper joining step S5), and the connection of the two beam members 30 is completed.

According to the connecting structure of the beam member 30 of the present embodiment, the two connecting member side reference holes 31c provided in the beam connecting member 31 are provided in the two beam member 30s, respectively. Since the two beam members 30 are connected in a state of matching with, a plurality of screw holes 31d arranged based on the connecting member side reference holes 31c and a plurality of screw holes 31d provided in each beam member 30. It coincides with the position of the beam insertion hole 30k. Therefore, it is possible to insert the bolt 7 in a state where the two beam members 30 and the beam connecting member 31 are arranged in a state where the positions of the beam insertion hole 30k and the screw hole 31d to be overlapped are all overlapped. be. Therefore, it is possible to easily connect the two beam members 30 by screwing the bolts 7 inserted into the beam insertion holes 30k.

Further, since the positions of the edges 30a with respect to the beam side reference holes 30j in each beam member 30 are set based on the distance between the two connecting material side reference holes 31c, the positions of the two connecting material side reference holes 31c and It is possible to bring the edges 30a of each beam member 30 into contact with each other and abut each other in a state where the positions of the beam side reference holes 30j of each beam member 30 match. Therefore, since the edges 30a of the beam members 30 are brought into contact with each other and connected to each other, it is possible to suppress the occurrence of bending of the beam 3 at the connecting portion of the two beam members 30.

Further, since the lower outer surface portion 31b forming the same plane of the beam connecting member 31 inserted into the hollow portion 30b of each beam member 30, the two connecting member side reference holes 31c and the screwing holes 31d are provided. It is possible to further improve the positional accuracy of the screw holes 31d with respect to the two connecting member side reference holes 31c. Therefore, the plurality of beam insertion holes 30k of the beam member 30 and the plurality of screws of the beam connecting member 31 provided with the beam side reference hole 30j matching the two connecting member side reference holes 31c with higher position accuracy. It is possible to easily align the position with the hole 31d.

Further, the pin 9 which is inserted through the connecting material side reference hole 31c and the beam side reference hole 30j to align the two beam members 30 and the beam connecting material 31 is the connecting material side reference hole 31c and the beam side reference hole. Since the length of the columnar portion 9a fitted into the 30j is longer than the total thickness of the wall thickness of the lower surface portion 30f of the beam member 30 and the wall thickness of the beam connecting member 31, the reference hole 31c on the connecting member side and the beam side It is possible to arrange the cylindrical portion 9a of the pin 9 in the reference hole 30j. Therefore, the centers of the connecting material side reference hole 31c and the beam side reference hole 30j can be aligned with each other. Therefore, it is possible to align the two beam members 30 and the beam connecting member 31 with higher accuracy.

Further, since the clearance between the connecting material side reference hole 31c and the beam side reference hole 30j and the columnar portion 9a is smaller than the clearance between the beam insertion hole 30k and the bolt 7, the connecting material side reference hole 31c and the beam side reference hole 30j By fitting the columnar portion 9a before the bolt 7, it is possible to easily screw the plurality of bolts 7 inserted into the beam insertion holes 30k through the screw holes 31d.

In the above embodiment, the beam side reference hole 30j into which the pin 9 is fitted and the connecting member side reference hole 31c are provided on the lower surface portion 30f and the lower outer surface portion 31b located on the lower surface side of the beam 3.

For example, the reference hole into which the pin is inserted may be provided only on the upper surface side of the beam member and the beam connecting member, or on both the upper and lower surfaces.
Further, in the above embodiment, the beam member 30 and the beam connecting member 31 are joined first on the lower surface side of the beam 3, and then the beam member 30 and the beam connecting member 31 are joined on the upper surface side of the beam 3. The method has been explained, but it is not limited to this. For example, in the case where the pin is fitted on the upper surface side, the beam member and the beam connecting material may be joined first on the upper surface side, and then the beam member and the beam connecting material may be joined on the lower surface side. do not have.

In the above embodiment, the connecting structure of the long timber in which the two beam members 30 are connected in the longitudinal direction and the method of connecting the long timbers have been described, but the long timbers are not necessarily connected in the longitudinal direction. It does not have to be connected. For example, even if two long members are connected at a predetermined angle, the edge of one long member is brought into contact with the other long member and protrudes from the edge of one long member. The long material connecting material enters the other long material side and is hung over the two long materials, and the positions of the two connecting material side reference holes provided in the long material connecting material and each of them. It does not matter if they are connected in a state where the positions of the reference holes on the long material side provided in the long material match.

According to the connecting structure of the two beam members 30 of the present embodiment, the lower surface portions 30f of the two beam members 30 are butted against each other, and the lower surface portions 30f are hung from the two beam members 30 from both sides. Since a single drill screw 8 is screwed and fastened to the lower outer surface portion 31b and the contact plate portion 32a to be sandwiched, a clearance is generated between the drill screw 8 and the lower surface portion 30f in the connected state. do not have. Therefore, it is possible to provide a connecting structure of the beam members 30 in which the relative positions of the two connected beam members 30 are unlikely to change.

Further, since the lower surface portion 30f is sandwiched between the lower outer surface portion 31b and the contact plate portion 32a, which have higher rigidity than the two beam members 30 provided with the lower surface portion 30f, from both sides, even if it is a drill screw. Even if a bearing pressure acts on the lower surface portion 30f from 8, there is no space for the lower surface portion 30f to bulge in the thickness direction when the drill screw 8 bites into the lower surface portion 30f. Therefore, even if a bearing pressure acts on the lower surface portion 30f, the hole into which the drill screw 8 is screwed does not expand on the lower surface portion 30f, so that the relative position of the two connected beam members 30 is suppressed from changing. It is possible to do.

Further, when the lower surface portion 30f of the two beam members 30, the lower outer surface portion 31b and the contact plate portion 32a are fastened only by the bolts 7, the lower surface is between the screwed portions of the bolts 7 adjacent to each other. Floating is likely to occur between the lower surface portion 30f, the lower surface portion 30f that sandwiches the lower surface portion 30f from both sides, and the lower outer surface portion 31b and the contact plate portion 32a. According to the connecting structure of the two beam members 30, the drill screw 8 is screwed between the screwed portions of the bolts 7 adjacent to each other, so that the screwed portions of the bolts 7 are brought into close contact with each other by the drill screw 8. It is possible to let it. Therefore, it is possible to more reliably suppress the change in the relative position of the two connected beam members 30.

Further, a bolt 7 inserted into the contact plate portion 32a and the lower surface portion 30f is screwed into the screw hole 31d provided in the lower outer surface portion 31b of the lower outer surface portion 31b and the contact plate portion 32a. Therefore, it is possible to connect the two beam members 30 without using a nut.

Further, according to the method of connecting the beam members 30 of the present embodiment, the lower surface portions 30f of the two beam members 30 are butted against each other and the lower surface portions 30f are sandwiched between the two beam members 30 from both sides. Since a single drill screw 8 is screwed and fastened to the lower outer surface portion 31b and the contact plate portion 32a, no clearance is generated between the two connected beam members 30 and the drill screw 8. Therefore, it is possible to provide a method of connecting the beam members 30 in which the relative positions of the two connected beam members 30 are unlikely to change.

Further, in the above embodiment, an example in which two beam-side reference holes 30j are provided in each beam member 30 and four connecting member-side reference holes 31c are provided in the beam connecting member 31 has been described. However, at least one beam-side reference hole may be provided in each beam member, and one connecting member-side reference hole may be provided on both ends of the beam connecting member.

Further, in the above embodiment, an example in which the bolt 7 is screwed into the screw hole 31d provided in the beam connecting member 31 has been described, but the present invention is not limited to this. For example, the beam connecting member may be provided with an insertion hole through which a bolt is inserted, and a nut may be screwed into and fastened to the bolt inserted together with the contact plate portion and the lower surface portion.
